How to reposition primary menu, title text on slider images & full-width footer?

First of all, I am definitely using .ORG and a Child Theme. I unfortunately cannot provide a web link but have attached pictures below.

I would like to find out if it is possible to:

1) Shift the primary menu up, to align it with the header image.

I did manage to do this by using:

#menu-primary {
top: -30px;
left: 300px;
}

However, the mobile version of the site would then move the primary menu waay off the screen in mobile view, so this was not suitable.

2) I also wish to re-position the title text of the slider (featured images) to the top-right hand corner and into a box. If this is not possible, whether there are any very good, free sliders that will do the same? I am yet to find one.
